AnthoLume Frontend Agent Guide

Read this file for work in frontend/. Also follow the repository root guide at ../AGENTS.md.

1) Stack

• Package manager: bun
• Framework: React + Vite
• Data fetching: React Query
• API generation: Orval
• Linting: ESLint + Tailwind plugin
• Formatting: Prettier

2) Conventions

• Use local icon components from src/icons/.
• Do not add external icon libraries.
• Prefer generated types from src/generated/model/ over any.
• Avoid custom class names in JSX className values unless the Tailwind lint config already allows them.
• For decorative icons in inputs or labels, disable hover styling via the icon component API rather than overriding it ad hoc.
• Prefer LoadingState for result-area loading indicators; avoid early returns that unmount search/filter forms during fetches.

3) Generated API client

• Do not edit src/generated/** directly.
• Edit ../api/v1/openapi.yaml and regenerate instead.
• Regenerate with: bun run generate:api

Important behavior

• The generated client returns { data, status, headers } for both success and error responses.
• Do not assume non-2xx responses throw.
• Check response.status and response shape before treating a request as successful.

4) Auth / Query State

• When changing auth flows, account for React Query cache state.
• Pay special attention to /api/v1/auth/me.
• A local auth state update may not be enough if cached query data still reflects a previous auth state.

5) Commands

• Lint: bun run lint
• Typecheck: bun run typecheck
• Lint fix: bun run lint:fix
• Format check: bun run format
• Format fix: bun run format:fix
• Build: bun run build
• Generate API client: bun run generate:api

6) Validation Notes

• ESLint ignores src/generated/**.
• Frontend unit tests use Vitest and live alongside source as src/**/*.test.ts(x).
• Read TESTING_STRATEGY.md before adding or expanding frontend tests.
• Prefer tests for meaningful app behavior, branching logic, side effects, and user-visible outcomes.
• Avoid low-value tests that mainly assert exact styling classes, duplicate existing coverage, or re-test framework/library behavior.
• bun run lint includes test files but does not typecheck.
• Use bun run typecheck to run TypeScript validation for app code and colocated tests without a full production build.
• Run frontend tests with bun run test.
• bun run build still runs tsc && vite build, so unrelated TypeScript issues elsewhere in src/ can fail the build.
• When possible, validate changed files directly before escalating to full-project fixes.

7) Updating This File

After completing a frontend task, update this file if you learned something general that would help future frontend agents.

Rules for updates:

• Add only frontend-wide guidance.
• Do not record one-off task history.
• Keep updates concise and action-oriented.
• Prefer notes that prevent repeated mistakes.
